Matchmaking API

A guide to the Health Connect Matchmaking API.

Overview

The Matchmaking API allows your app to discover other apps and devices that can write health data that your app has permission to read. This helps users connect their favorite data sources to your app with less friction.

The Matchmaking screen discovers Health Connect-compatible apps and devices. It then cross-references your app's required read permissions with the write capabilities of those apps and devices. The screen displays apps and devices that have declared, but not yet granted, write permissions for at least one of the specified record types that your app is permitted to read.

Before you begin

This guide assumes you have already configured Health Connect in your app and have an instance of HealthConnectClient available.

Beta setup

The Matchmaking API is available through an update to Health Connect that is gradually rolling out to production devices, with 100% availability expected by early June 2026. To test matchmaking features before this update is broadly available, enroll your test device in the Android Beta program for early access.

Check Health Connect availability

Before attempting to use Health Connect, your app should verify that Health Connect is available on the user's device. Health Connect may not be installed on the user's device, or it could be disabled.

Use HealthConnectClient.getSdkStatus() to check for availability. If Health Connect is not available, prompt the user to install or update Health Connect from the Google Play Store.

Check feature availability

To determine whether a user's device supports matchmaking on Health Connect, check for the availability of FEATURE_MATCHMAKING:

if (healthConnectClient
    .features
    .getFeatureStatus(
    HealthConnectFeatures.FEATURE_MATCHMAKING
    ) == HealthConnectFeatures.FEATURE_STATUS_AVAILABLE) {

// Feature is available
} else {
// Feature isn't available
}

Implementation

The matchmaking flow is launched using a MatchmakingRequest. This request defines which record types you want your app to collect, and lets you include or exclude specific data sources such as apps or devices:

• recordTypes: A set of Record classes such as StepsRecord::class. If empty, the flow considers all record types your app has read permissions for.
• includedDataSources: A set of DataOrigin objects to exclusively include.
• excludedDataSources: A set of DataOrigin objects to exclude.

Follow these steps to integrate the Matchmaking API into your application.

Check if matchmaking is possible

Before showing a matchmaking entry point, use checkIfMatchmakingIsPossible() to determine if there are any relevant matching apps or devices for the requested record types:

suspend fun checkMatchmakingPossible(healthConnectClient: HealthConnectClient) {
    val request = MatchmakingRequest(recordTypes = setOf(StepsRecord::class))
    val response = healthConnectClient.checkIfMatchmakingIsPossible(request)

    if (response.isMatchmakingPossible) {
        // Relevant apps or devices found. Show entry point to launch flow.
    } else {
        // Handle case where no new data sources are available
    }
}

We recommend checking if matchmaking is possible on an ongoing basis. Users might later install additional apps or connect devices with mutually compatible data types. A common approach is to check each time your app starts. If it returns true, show an entry point to launch the matchmaking flow.

Launch the Matchmaking flow

If matchmaking is possible, use createMatchmakingIntent() to get an Intent to launch the Health Connect flow, then launch it using the Activity Result API:

// Create the matchmaking launcher
val matchmakingLauncher = registerForActivityResult(
    ActivityResultContracts.StartActivityForResult()
) { result ->
    if (result.resultCode == Activity.RESULT_OK) {
        // Matchmaking finished successfully.
        // User successfully granted at least one permission.
    } else {
        // User canceled flow or didn't grant permissions.
    }
}

fun launchMatchmaking(healthConnectClient: HealthConnectClient) {
    val request = MatchmakingRequest(recordTypes = setOf(StepsRecord::class))
    val intent = healthConnectClient.createMatchmakingIntent(request)
    matchmakingLauncher.launch(intent)
}

By launching this intent, Health Connect displays a screen where users can see compatible apps and devices, and choose to connect them to share data with your app.
